Track Day Tire Pressures'

[1795]

I would also add this suggestion. When you go out on your first lap you will want to warm your tires up so that they grip better, do not run hard on cold tires, you increase the likelihood of an accident. Go at slow to moderate speed on the straights and weave the car from side to side. This will build heat into the tires and increase grip. Make sure that you stop weaving prior to corners. If you are able to check tire temps, that will help you find the right pressure. Yo want even temps across the face of the tire. Take a temp at the outside, middle and inside of the tread on each tire. Camber will affect the temp readings, as the more camber the more one section (inside or outside) of the tire will be contacting the pavement then the opposite side of the tire. High temps in the middle, as opposed to edges, suggest over inflation. Lower temps in the middle as opposed to edges suggests under inflation. Temps do not need to be exactly the same, you just want to address differences of 5 degrees or more.
